NWS15 150K Meter Mineral Tank System

Built for homes with heavy water demand, the NWS15 150K Meter Mineral Tank System from Nelsen Water Solutions delivers 150,000 grains of softening capacity through a high-flow 1-1/2" metered control valve. As a single-tank platform, it forms a capable, efficient backbone for residential and light-commercial softening, with the flexibility to size the brine side to your site.

Metered efficiency at high capacity

The mineral-tank assembly arrives with the Nelsen Water Solutions 1-1/2" metered control valve, commercial distributors, a gravel underbed for even flow distribution, and high-capacity resin matched to the 150,000-grain rating. Metering is the key efficiency feature here: the valve initiates regeneration based on the water you actually use, rather than running on a fixed timer, which keeps salt and water consumption in check over the long run while making sure capacity is available when household demand peaks.

• 150,000-grain softening capacity
• 1-1/2" lead-free brass metered control valve
• Commercial distributors, gravel bed, and high-capacity resin included
• Usage-based regeneration to conserve salt and water
• Brine tank sold separately for configuration flexibility
• Progressive Flow option: add CL-COM-34-12 cord plus CL-NHBP-15 bypass per valve

Ordering the brine tank separately lets you choose a salt-storage vessel that fits your available space and operating preferences instead of accepting a bundled size. For Progressive Flow installations, Nelsen recommends adding one CL-COM-34-12 communication cord for the system and one CL-NHBP-15 no-hard-water bypass for each valve. Match the 150,000-grain capacity to your measured hardness and peak demand for the best results, and keep up with routine salt refills to maintain consistent softening. For a high-capacity, demand-regenerated softener with a flexible brine setup, this Nelsen 150K system is a strong, adaptable choice for larger homes.

Proper installation pairs the system with a bypass so the unit can be isolated for service without shutting off water to the home, and locates it ahead of the water heater to protect that appliance from scale. A nearby drain for regeneration discharge and a grounded outlet for the control are also required. As with any softener, a recent water analysis covering hardness, iron, and pH ensures the system is set up correctly for your specific supply from day one.
